The study, which experts believe may be the first of its kind, is expected to be looking for abnormalities or mutations in Lanza's DNA.

Connecticut Medical Examiner H. Wayne Carver has reached out to University of Connecticut's geneticists to conduct the study.

University of Connecticut spokesperson Tom Green says Carver "has asked for help from our department of genetics" and they are "willing to give any assistance they can."

Green said he could not provide details on the project, but said it has not begun and they are "standing by waiting to assist in any way we can."

Lanza, 20, carried out the massacre at Sandy Hook Elementary School in Newtown, Conn., just days before Christmas. His motives for the slaughter remain a mystery.

Geneticists not directly involved in the study said they are likely looking at Lanza's DNA to detect a mutation or abnormality that could increase the risk of aggressive or violent behavior. They could analyze Lanza's entire genome in great detail and try to find unexpected mutations.

This seems to be the first time a study of this nature has been conducted, but it raises concerns in some geneticists and others in the field that there could be a stigma attached to people with these genetic characteristics if they are able to be narrowed down.

Arthur Beaudet, a professor at Baylor College of Medicine, said the University of Connecticut geneticists are most likely trying to "detect clear abnormalities of what we would call a mutation in a gene…or gene abnormalities and there are some abnormalities that are related to aggressive behavior."

"They might look for mutations that might be associated with mental illnesses and ones that might also increase the risk for violence," said Beaudet, who is also the chairman of Baylor College of Medicine's department of molecular and human genetics.

Beaudet believes geneticists should be doing this type of research because there are "some mutations that are known to be associated with at least aggressive behavior if not violent behavior."

"I don't think any one of these mutations would explain all of (the mass shooters), but some of them would have mutations that might be causing both schizophrenia and related schizophrenia violent behavior," Beaudet said. "I think we could learn more about it and we should learn more about it."

Beaudet noted that studying the genes of murderers is controversial because there is a risk that those with similar genetic characteristics could possibly be discriminated against or stigmatized, but he still thinks the research would be helpful even if only a "fraction" may have the abnormality or mutation.

"Not all of these people will have identifiable genetic abnormalities," Beaudet said, adding that even if a genetic abnormality is found it may not be related to a "specific risk."

"By studying genetic abnormalities we can learn more about conditions better and who is at risk and what might be dramatic treatments," Beaudet said, adding if the gene abnormality is defined the "treatment to stop" other mass shootings or "decrease the risk is much approved."

Others in the field aren't so sure.

Dr. Harold Bursztajn, a professor of psychiatry at Harvard Medical School, is a leader in his field on this issue writing extensively on genetic discrimination. He questions what the University of Connecticut researchers could "even be looking for at this point."
